SURE-STOP ATTACHMENT FOR srANcHIoNs. 1

To all whom it may concern:

Be it known that I, MALCOLM B. MOYER, a

citizen of the United-States, residing at Montevideo, in the county of Chippewa State of Minnesota,-have invented certain new and useful Improvements in Sure-Stop Attachments for Stanchions; and I do declare the following to'be a full, clear, and exact description of the invention, such as will enable others skilled in theart to which it appertains to make and use the .same.

My invention relates broadly to improvements in cattle stanchions, and more particularly to the. sure-stops used in conjunction therewith for preventing the stock from inserting their heads between one side of the stanchion and the side of the stall.

Heretofore, numerous types of sure-stops have been secured to the stanchions by bolts, screws and the like, but it often occurs that some purchasers wish the stanchions furnished without the sure-stops while others invariable wish to use the latter. Further more, persons who have been using stanchions without sure-stops and who have found X that the application of the latter to such stanchions would be a great asset, demand a device of the class in question which may be easily attached to their stanchions. It therefore becomes highly expedient to provide some simple construction, whereby the surestop may be attached to or detached from. a stanchion more quicklyand easily than is possible when bolts or the like are used.

plates l0'su1tably pressed to conform sub-.

This end the invention aims to attain in a simple and efficient manner, provision being made whereby'even though a quick detach able connection isprovidedbetween the stop and the stanchion, such connection may not easily be released.

The quick detachable connection between the sure-stop and the stanchion is not only advantageous to the consumer, but to the manufacturer and salesman, since it is unnecessary to carry in stock two diflerent kinds of stanchions, one without and the other with sure-stops. On the other hand, by keeping a supply of stanchions and surestops on hand, such stanchi'ons may be quickly and easily equipped with sure-stopsif desired, or if sure-stops have been previously attached and are not desired by the purchaser, they may be easily removed.

With the above stated object in view, the invention consists of certain novel features of construction and of unique combinations N Specification of Letters P'atent. Patented Feb. 13, 1917. Application fiiea December 2, 1915; 'SerialNO. c4359. l I I i of parts to be hereinafter fully described and claimed,xthe descriptive'matter being supplemented by the accompanying drawing which constitutes a part of this appli- "cation.

' In this drawing:

Figure 1 is a side elevation of a stanchion showing in full'and dotted lines two of the steps necessary in applying one of the surestops to use;

Fig. 2 is a side elevation with parts broken away and in section, showing the sure-stop completely connected with the stanchion and Fig. 3 is a detail verticaltransverse section as viewed on the plane of the line 38 ofFig.2. f

p In specifically describing the invention, reference will be made to the drawing above briefly described by similar reference characters placed on corresponding parts throughout the several views. To this end,

the numeral 1 indicates broadly a stanchion stantially to the shape of the bars 2 and 3, such plates being riveted at 11 tosaid bar 2 and being, extended upwardly beyond the channeled side of the bar 3 to provide a pair of spaced guide flanges 12 clamped together by bolts 13 whose intermediate portions span the space, between said flanges and constitute abutrhents or coupling members for a purpose yet to be set forth. An additional bolt 14: is preferably passed through the plates 10 in the angle between the bars 2 and3., The clamp G'isidentical in construction with the clamp 5 and has its side plates 10 secured together and extended below the channeled side of the bar 4: to form guide flanges 12 connected by bolts 13 whose intermediate portions perform the same functions as said portions of the bolts 13.

The structure so far described, constitutes a common type of stanchion to which it is intended to attach a sure-stop bar. The bar in question is shown at 15 in the drawing.

of the arm 17 is formed with a pair of spaced notches 18 adapted to receive the bolts 13 In applying the bar 15 to the stanchion, the lower arm 17 is inserted between the outer ends of the flanges 12, being received snugly within the channel of the lower end bar 4. The outermost of the notches 18 is now engaged with the outermost bolt 13*, the bar 15 now standing approximately as shown in full lines in Fig. 1. The next operation is to swing said bar toward the stanchion and spring it longitudinally until the notch 18 near the end of the arm 16 may receive the outermost bolt 13. An appropriate part of the arm 16 is now struck a sharp downward and inward blow, thus springing such arm downwardly and forcing it inwardly until both of its notches 18 may receive their respective bolts 13. The

tension under which the bar 15 has been to insert its head between said bar and the left side of the stanchion (not shown), even though the bar 15 should be sprungby this attempt, such springing of the bar in question will have no tendency to loosen the detachable connections between the ends of said bar and the stanchion. On the contrary, inward springing of the bar 15 will tend to force the arms 16 and 17 respectively upward and downward, thereby causing such arms to contact more forcibly than beforewith the bolts 13 and 13 From the foregoing description, taken in connection with the accompanying drawing, it will be obvious that I have provided a simple, strong, inexpensive, durable and efficient sure-stop which may be quickly and easily attached or detached and which when applied to use will be held against loose movement in respect to the stanchion, this being partially due to the snug contact of the bolts 13 and 13 with the walls of the notches 18 and 18 but primarily to the fact that thearms 16 and 17 are received snugly in the channels of the end bars 3 and 4.

In the drawing, certain specific details of construction have been shown for illustrative purposes and in the preceding, such details have been described, but it is obvious that numerous changes may be made within the scope of theinvention as claimed without sacrificing any of the advantages thereof.

1 claim 1. The combination with a stanchion, of an upright resilient stop bar spaced laterally therefrom and sprung to place it under tension, and coacting coupling means on said stop-bar and stanchion held in detach- ?)ble engagement by the tension of said stop 2. The combination with a stanchion, of upper and lower abutments carried respectively by the upper and lower ends thereof, and a yieldable sure-stop sprung to place it under tension and having laterally projecting arms bearing respectively against one side of the upper abutment and the other side of the lower abutment, said arms having shoulders cooperating with said abutments, the tension of the sure-stop being exerted to retain the aforesaid shoulders and abutments in engagement.

3. The combination with a stanchion, of an upright yieldable sure-stop sprung to place it under tension, said sure-stop being detachably connected at one end to the stanchion and having at its other end a laterally projecting arm, a guide on the stanchion receiving said arm, and a transverse pin passing through the guide, the arm be ing formed with a notch receiving said pin and the tension of the sure-stop being exerted to retain the notch in engagement with the pin. V

4. The combination with a stanchion having at one end a channel bar, and a pair of plates projecting vertically from said bar beyond the channeled side thereof, of a yieldable sure-stop sprung to place it under tension and having one end detachably connected with the stanchion, said sure-stop having at its other end a laterally projecting arm received snugly in the channel of the aforesaid bar, and a transverse stop pin spanning the space between the two plates, the arm being formed with a notch receiving said pin andthe notch and pin being retained in engagement by the tension of the sure-stop.

5. A sure-stop for stanchions in the form of a resilient bar having laterally extending attaching arms at its upper and lower ends, such arms being formed with notches for cooperation with abutments on the stanchion, the notch in one arm being in the op posite side thereof from the notch in the other arm.

6. A sure-stop for stanchions formed of a single T-iron bar having its upper and lower ends bent laterally in the same direction to form upper and lower attaching arms, the web of said bar being disposed adjacent the upper side of the upper arm and the lower side of the lower arm and being formed with notches adjacent the free ends of said arms for cooperation with abutments on the stanchion.

7. In combination, a stanchion including upper and lower channel iron bars with their channels disposed respectively upwardly and downwardly, an upright side bar extending between one end of said channel iron bars, couplings securing said upright bar to said channel iron bars, said couplings each comprising a pair of plates clamped in contact with opposite sides of the bars and projecting vertically beyond the channeled sides of the aforesaid channel iron bars, a pair of bolts passing through the projecting portions of the plates of each coupling and disposed adjacent the aforesaid channeled sides of the channel iron and the lower side of the lower arm, the

portion of said web on the aforesaid arms having notches, the entire bar being sprung longitudinally to place it under tension and having its arms received in the channels of the channel iron bars with their notches in turn receiving the aforesaid bolts, the latter and the notches being held in yielding detachable engagement by the tension of the aforesaid stop bar.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
